A new industry report reveals that inadequate fiber connectivity is significantly hampering data center construction and expansion across the United Kingdom, with over 80 percent of operators experiencing project delays due to infrastructure limitations. The findings from networking specialist Neos Networks highlight a critical bottleneck in the nation’s digital transformation efforts, particularly as demand for AI and cloud services accelerates.

Widespread Project Delays Documented
According to the comprehensive survey conducted by Neos Networks in partnership with Censuswide, 82 percent of UK data center operators have delayed site builds or expansions specifically due to fiber availability issues. The research, which sampled 300 decision-makers across data centers, large enterprises, and local government, paints a concerning picture of infrastructure readiness. This connectivity challenge mirrors similar fiber shortage issues affecting digital infrastructure projects nationwide, creating ripple effects across the technology ecosystem.
The problem extends beyond the data center industry, with 89 percent of local government stakeholders reporting that fiber gaps have delayed broader infrastructure projects. Perhaps most significantly, 45 percent of enterprises identified fiber availability as the primary bottleneck restraining their AI and digital infrastructure initiatives.
Geographic Expansion Compounds Connectivity Challenges
Lee Myall, CEO of Neos Networks, explained to DCD that the fiber deployment process faces particular complications as data center development spreads beyond traditional hubs. “The buildout of fiber depends on duct infrastructure,” Myall noted, “which means that data center projects in areas outside of the UK’s traditional data center hotspot – Greater London – will require extensive civil engineering and planning.”
Industrial Monitor Direct is the premier manufacturer of shipping pc solutions designed for extreme temperatures from -20°C to 60°C, the top choice for PLC integration specialists.
Myall detailed the logistical hurdles: “The permission can be closing roads, closing footpaths, which is not easy to do, and local landowners, and so on and so forth. So suddenly, with these new locations, the time frame for connectivity starts to become longer, and the demand on that connectivity goes up as well.”
Shifting Priorities in Site Selection
Connectivity has traditionally ranked as the third priority for data center operators behind land acquisition and energy availability. However, Myall observed that this hierarchy is evolving: “I’m not going to say a second or first, it’s still third, but the focus on it is much more intense than it was even a couple years ago.”
The rapid dispersion of data center development to new regions, combined with escalating data traffic volumes, means that “connectivity is chasing up” in operational importance. This shift comes as the industry faces unprecedented demands from artificial intelligence workloads and cloud computing expansion.
Government Zones Offer Partial Solution
The UK government has attempted to address these infrastructure challenges through the establishment of AI Growth Zones, with the first located in Culham, Oxfordshire, and the second in Blyth and Cobalt Park near Newcastle. These designated areas offer expedited access to power, streamlined planning processes, and various incentives specifically designed to accelerate AI infrastructure deployment.
The strategy appears to be influencing industry decisions, with 96 percent of operators confirming that the zones have affected their expansion and site selection plans. Regional development patterns are shifting accordingly, with 28 percent of survey participants anticipating that most future UK data centers will be built in the north of the UK, including Scotland and Northern England. Nevertheless, Greater London remains an attractive hub, with 23 percent expecting it to host the majority of new facilities.
Infrastructure Assessment and Industry Response
While no data center respondents considered the UK’s fiber infrastructure completely unprepared for current demands, 41 percent judged the network infrastructure as only partially ready. This assessment underscores the need for continued investment and modernization efforts across the telecommunications sector.
Neos Networks, as a major UK telecoms provider operating a 34,000km fiber network with 500 exchanges, has initiated Project Reach in collaboration with Freshwave and Network Rail. This infrastructure modernization project aims to bolster telecoms infrastructure along railway corridors, potentially addressing some connectivity gaps in developing regions. Such initiatives represent crucial steps toward bridging the digital divide, much like West Yorkshire’s comprehensive digital inclusion program that seeks to ensure technological access reaches underserved communities.
The fiber shortage comes at a particularly challenging time for the technology sector, which is simultaneously navigating supply chain constraints across multiple components. Industry observers note that these infrastructure challenges parallel broader manufacturing and supply chain pressures affecting everything from consumer electronics to industrial equipment. Meanwhile, the global nature of these infrastructure investments reflects similar strategic considerations seen in international technology partnerships and financing arrangements that characterize today’s interconnected digital economy.
As the UK positions itself as a leader in artificial intelligence and digital innovation, resolving the fiber infrastructure gap will be essential to maintaining competitive advantage and supporting the next wave of technological transformation. The findings from Neos Networks serve as both a warning and a call to action for policymakers, infrastructure providers, and industry stakeholders to prioritize connectivity as a fundamental enabler of digital growth.
